• Resumen

  • This paper is a case study of the efficiency of a 2.5 MW wind turbine gearbox including the influence of each gearbox element: gear tooth geometry, rolling bearings and oil formulation. The power loss model used to predict the gearbox efficiency was previously validated with experimental results. The calculations showed that the efficiency of a wind turbine gearbox can be improved by selecting different wind turbine gear oil formulations, modifying gear tooth geometry. The energy savings can be even more significant if both gear tooth geometry and oil formulation are adequately selected.
